Description

Technical Field

[0001] The present invention relates to the technical field of defrosting equipment, and specifically to a defrosting device for a cold chain logistics warehouse. Background Art

[0002] During the operation of a cold chain warehouse, due to factors such as the opening and closing of the warehouse door when accessing goods, the moisture carried by the stored goods themselves, and the water vapor in the air, it is easy to cause serious condensation, frosting, and icing on the inner wall of the cold chain warehouse. When icing and frosting occur, the heat exchange efficiency of the cold chain warehouse decreases, increasing the operating energy consumption of the cold chain warehouse, thereby increasing the operating and maintenance costs of the cold chain warehouse.

[0003] A defrosting mechanism for a cold chain logistics warehouse disclosed in the existing patent (Publication No.: CN219454399U) defrosts through a first defrosting scraper when an unmanned vehicle enters the cold chain logistics warehouse. Its defrosting efficiency is relatively high, and the elevator can enable the first defrosting scraper to defrost warehouses at different heights, improving the working stability and working efficiency of the device.

[0004] However, the above technical solution still has certain defects. This device scrapes the ice and frost on the inner wall of the warehouse through a scraping knife. Since the ice has a certain hardness and thickness and adheres firmly to the inner wall of the warehouse, it may be necessary to scrape repeatedly to scrape the ice and frost off the inner wall, which relatively affects the scraping efficiency. At the same time, when scraping, the ice may splash and fall to the ground and cannot enter the collection box, affecting the refrigeration effect of the warehouse. Therefore, a defrosting device for a cold chain logistics warehouse is proposed. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a defrosting device for a cold chain logistics warehouse to solve the technical problems of difficult removal of ice and frost and easy falling to the ground mentioned in the above background.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A defrosting device for a cold chain logistics warehouse, including a mobile vehicle, one side of the top of the mobile vehicle is provided with a defrosting component, and one side of the bottom of the mobile vehicle is provided with a collection component;

[0007] The defrosting component includes a fixed sleeve fixed to one side of the mobile vehicle. A telescopic sleeve is slidably connected inside the fixed sleeve. An L-shaped fixing plate is provided at the rear end of the telescopic sleeve. A servo motor is installed on the L-shaped fixing plate. An ice scraper is fixed to the output end of the servo motor. A scraper is fixed to one side of the top end of the telescopic sleeve on one side of the ice scraper. And a belt is rotatably connected to one end of the ice scraper close to the servo motor. A round rod is rotatably connected to the inner wall of the belt on the side away from the ice scraper. A disc is fixed to one end of the round rod. A round shaft is fixed to the end of the disc away from the round rod. A moving block is slidably connected to the surface of the round shaft. A cross bar is fixed to the end of the moving block away from the round shaft. The end of the cross bar away from the moving block penetrates through one side of the telescopic sleeve and is fixed with a ice knocking knife. A first electric push rod is installed on one side of the fixed sleeve. The end of the movable rod of the first electric push rod is installed with a square plate fixed to one side of the telescopic sleeve;

[0008] The collection component includes a connecting plate installed at the front end of the fixed sleeve. A second electric push rod is fixed to one side of the connecting plate. An extrusion rod is fixed to the end of the movable rod of the second electric push rod. A collection cylinder is slid on the surface of the extrusion rod. A piston cylinder is fixed inside the mobile vehicle. A piston rod is slid on the inner wall of the piston cylinder. A return spring installed inside the piston cylinder is sleeved on the surface of the piston rod. A multi-stage telescopic tube is connected to the surface of the piston cylinder. A smoothing rod is fixed to one side of the multi-stage telescopic tube. A collection box installed inside the mobile vehicle is provided at the bottom end of the smoothing rod.

[0009] As a preferred technical solution, universal wheels are installed at the four corners of the bottom end of the mobile vehicle. The collection box is slidably connected to the mobile vehicle.

[0010] As a preferred technical solution, a baffle is fixed to the end of the telescopic sleeve away from the scraper. A spring telescopic rod is fixed inside the baffle. A telescopic plate slidably connected to the inner wall of the baffle is provided at the end of the spring telescopic rod. A roller is rotatably connected to the top end of the telescopic plate.

[0011] As a preferred technical solution, the cross bar is slidably connected to the telescopic sleeve. The ice knocking knife is attached to one side of the scraper.

[0012] As a preferred technical solution, a rack attached to the inner wall of the collection cylinder is fixed to one side of the extrusion rod. A ratchet gear meshing with the rack is provided at one side of the bottom end of the rack. A base rod is fixed to the center of the ratchet gear. A long plate is fixed to the surface of the base rod.

[0013] As a preferred technical solution, a torsion spring is installed at the end of the base rod away from the ratchet gear. A long groove is opened at the lower end of the inner wall of the collection cylinder. The long groove penetrates through the bottom end of the collection cylinder.

[0014] As a preferred technical solution, the long plate is installed and fitted inside the long groove. The opening direction of the long groove faces the collection box.

[0015] As a preferred technical solution, the running track of the extrusion rod is directly opposite to the piston rod, and the top ends of the piston cylinder and the moving vehicle are on the same horizontal plane.

[0016] In summary, the present invention mainly has the following beneficial effects:

[0017] In the present invention, the ice scraper scrapes the ice frost on the inner wall of the warehouse. At the same time, the servo motor drives the ice removing knife and the belt to rotate. The rotation of the ice removing knife can break and thin some relatively thick ice layers on the inner wall of the warehouse, avoiding the situation that the ice scraper cannot better scrape some relatively thick ice frost. At the same time, the moving block drives the ice knocking knife to repeatedly scrape and knock the front end of the ice scraper, loosen the ice frost, further improve the scraping efficiency of the ice scraper for the ice frost on the inner wall of the warehouse, avoid the residual ice frost from affecting the refrigeration effect of the warehouse, and improve the operation efficiency of the warehouse.

[0018] When the extrusion rod drives the rack to reset in the present invention, a negative pressure will be generated inside the collection cylinder, thereby sucking and cleaning the ice fragments that have fallen to the ground, and the ice slag is transported to the long groove through the collection cylinder. When the extrusion rod is compressed, it will drive the ratchet gear to rotate, and the ratchet gear drives the long plate to rotate through the base rod, so that the ice slag in the long groove falls into the collection box through the rotation of the long plate, facilitating the subsequent continuous cleaning work of the ice slag, thereby greatly saving manpower, improving the cleanliness of the warehouse, enhancing the efficiency of the defrosting operation, ensuring the quality of the stored items. At the same time, through the repeated movement of the smoothing rod inside the collection box, the scraped ice frost and the absorbed fragments can be better stored inside the collection box, avoiding accumulation, making the broken ice inside the collection box more compact, and facilitating the subsequent processing by the staff.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation to the present invention.

[0031] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0032] A defrosting device for a cold chain logistics warehouse, as Figure 1-8 shown, includes a mobile vehicle 100. One side of the top end of the mobile vehicle 100 is provided with a defrosting component 200, and one side of the bottom end of the mobile vehicle 100 is provided with a collection component 300;

[0033] The defrosting component 200 includes a fixed sleeve 210 fixed to one side of the mobile vehicle 100. A telescopic sleeve 220 is slidably connected inside the fixed sleeve 210. An L-shaped fixing plate 230 is provided at the rear end of the telescopic sleeve 220. A servo motor 240 is installed on the L-shaped fixing plate 230. An ice scraper 250 is fixed to the output end of the servo motor 240. A scraper 260 fixed to one side of the top end of the telescopic sleeve 220 is provided on one side of the ice scraper 250. And a belt 2910 is rotatably connected to one end of the ice scraper 250 close to the servo motor 240. A round rod 2920 is rotatably connected to the inner wall of the belt 2910 on the side far from the ice scraper 250. A disc 2930 is fixed to one end of the round rod 2920. A round shaft 2940 is fixed to the end of the disc 2930 far from the round rod 2920. A moving block 2950 is slidably connected to the surface of the round shaft 2940. A cross bar 2960 is fixed to the end of the moving block 2950 far from the round shaft 2940. The end of the cross bar 2960 far from the moving block 2950 penetrates through one side of the telescopic sleeve 220 and is fixed with a ice knocking knife 2970. A first electric push rod 2980 is installed on one side of the fixed sleeve 210. A square plate 2990 fixed to one side of the telescopic sleeve 220 is installed at the end of the movable rod of the first electric push rod 2980;

[0034] The collection component 300 includes a connecting plate 310 installed at the front end of the fixed sleeve 210. A second electric push rod 320 is fixed to one side of the connecting plate 310. An extrusion rod 330 is fixed to the end of the movable rod of the second electric push rod 320. A collection cylinder 340 slides on the surface of the extrusion rod 330. A rack 350 attached to the inner wall of the collection cylinder 340 is fixed to one side of the extrusion rod 330. A ratchet gear 360 engaged with the rack 350 is provided on one side at the bottom end of the rack 350. A base rod 361 is fixed to the center of the ratchet gear 360. A long plate 370 is fixed to the surface of the base rod 361. A torsion spring 362 is installed at the end of the base rod 361 far from the ratchet gear 360. A long groove 341 is opened at the lower end of the inner wall of the collection cylinder 340. The long groove 341 penetrates through the bottom end of the collection cylinder 340. A piston cylinder 380 is fixed inside the mobile vehicle 100. A piston rod 390 slides inside the inner wall of the piston cylinder 380. A return spring 3910 installed inside the piston cylinder 380 is sleeved on the surface of the piston rod 390. A multi-stage telescopic tube 3920 is connected to the surface of the piston cylinder 380. A smoothing rod 3930 is fixed to one side of the multi-stage telescopic tube 3920. A collection box 3940 installed inside the mobile vehicle 100 is provided at the bottom end of the smoothing rod 3930.

[0035] By controlling the displacement of the mobile vehicle 100 to a specified position, the scraping blade 260 is made to fit against the inner wall of the warehouse. Subsequently, the first electric push rod 2980 and the servo motor 240 are started. The first electric push rod 2980 drives the telescopic sleeve 220 to move upward through the square plate 2990, thereby enabling the scraping blade 260 to scrape the ice on the inner wall of the warehouse. At the same time, the servo motor 240 drives the ice scraping knife 250 and the belt 2910 to rotate. The rotation of the ice scraping knife 250 can break and thin some relatively thick ice layers on the inner wall of the warehouse, preventing the scraping blade 260 from being unable to scrape some relatively thick ice better. Meanwhile, the belt 2910 drives the round rod 2920 to rotate, and the round rod 2920 drives the disc 2930 and the round shaft 2940 to rotate synchronously, thereby enabling the moving block 2950 to move reciprocally. The moving block 2950 drives the ice knocking knife 2970 through the cross bar 2960 to repeatedly scrape and knock the front end of the scraping blade 260, loosening the ice, further improving the scraping efficiency of the scraping blade 260 on the ice of the inner wall of the warehouse, preventing the residual ice from affecting the refrigeration effect of the warehouse, enhancing the operation efficiency of the warehouse. When the ice scraping is completed, the second electric push rod 320 is started, driving the extrusion rod 330 to move inside the collection cylinder 340. The extrusion rod 330 drives the rack 350 to move synchronously. When the extrusion rod 330 drives the rack 350 to reset, a negative pressure is generated inside the collection cylinder 340, thereby sucking and cleaning the ice fragments that have fallen to the ground. The ice slag is conveyed through the collection cylinder 340 to the long groove 341. When the extrusion rod 330 is compressed, it drives the ratchet gear 360 to rotate, and the ratchet gear 360 drives the long plate 370 to rotate through the base rod 361, thereby enabling the ice slag inside the long groove 341 to fall into the collection box 3940 through the rotation of the long plate 370. By setting the torsion spring 362, the long plate 370 can be reset, facilitating subsequent continuous cleaning work of the ice slag, thus greatly saving manpower, improving the cleanliness of the warehouse, enhancing the efficiency of the defrosting operation, ensuring the quality of the stored items. At the same time, the movement of the extrusion rod 330 compresses the piston rod 390, causing the piston rod 390 to stretch the spring and compress the gas inside the piston cylinder 380. The gas enters the multi-stage telescopic tube 3920 and causes it to extend, thereby driving the smoothing rod 3930 to move repeatedly inside the collection box 3940, facilitating the better storage of the scraped ice and the absorbed debris inside the collection box 3940, preventing accumulation, making the crushed ice inside the collection box 3940 more compact, and facilitating subsequent processing by the staff.

[0036] Please refer particularly to Figures 1 to 4, universal wheels 110 are installed at the four corners of the bottom end of the mobile vehicle 100. The collection box 3940 is slidably connected to the mobile vehicle 100. One end of the top of the telescopic sleeve 220, which is far from the scraping knife 260, is fixed with a baffle 270. A spring telescopic rod 280 is fixed inside the baffle 270. The end of the spring telescopic rod 280 is provided with a telescopic plate 290 slidably connected to the inner wall of the baffle 270. The top of the telescopic plate 290 is rotatably connected with a roller 291.

[0037] By setting the telescopic plate 290, it can better fit the inner wall of the cold chain logistics warehouse, preventing a large amount of debris from flying everywhere when the ice scraping knife 250 rotates. By setting the roller 291, it is convenient to move while better fitting the inner wall.

[0038] Please refer particularly to Figure 3 and Figure 5 , the cross bar 2960 is slidably connected to the telescopic sleeve 220, and the ice knocking knife 2970 is attached to one side of the scraping knife 260.

[0039] By setting the ice knocking knife 2970, it is more convenient for the scraping knife 260 to defrost and deice the inner wall of the warehouse.

[0040] Please refer particularly to Figures 6 to 8 , the long board 370 is installed and fitted in the long groove 341. The opening direction of the long groove 341 is directly opposite to the collection box 3940. The running track of the extrusion rod 330 is directly opposite to the piston rod 390. The top of the piston cylinder 380 and the top of the mobile vehicle 100 are on the same horizontal plane.

[0041] By making the running track of the extrusion rod 330 directly opposite to the piston rod 390, it is convenient to synchronously extrude the piston rod 390.

[0042] In use, the ice scraper 260 is used to scrape the ice on the inner wall of the warehouse. At the same time, the servo motor 240 drives the ice removal knife 250 and the belt 2910 to rotate. The rotation of the ice removal knife 250 can break and thin some thicker ice layers on the inner wall of the warehouse, preventing the ice scraper 260 from being unable to scrape some thicker ice better. At the same time, the moving block 2950 moves reciprocally, and the moving block 2950 drives the ice knocking knife 2970 to repeatedly scrape and knock the front end of the ice scraper 260 through the cross bar 2960, loosening the ice, further improving the scraping efficiency of the ice scraper 260 for the ice on the inner wall of the warehouse, preventing the remaining ice from affecting the refrigeration effect of the warehouse, and improving the operation efficiency of the warehouse. When the ice scraping is completed, the second electric push rod 320 is started to drive the extrusion rod 330 to move inside the collection cylinder 340. The extrusion rod 330 drives the rack 350 to move synchronously. When the extrusion rod 330 drives the rack 350 to reset, a negative pressure will be generated inside the collection cylinder 340, thereby sucking and cleaning the ice chips that have fallen to the ground. The ice chips are transported through the collection cylinder 340 to the long groove 341 and then fall into the collection box 3940. By setting the torsion spring 362, the long board 370 can be reset, facilitating subsequent continuous cleaning of the ice chips, thus greatly saving manpower, improving the cleanliness of the warehouse, enhancing the efficiency of the defrosting operation, ensuring the quality of the stored items. At the same time, the flattening rod 3930 moves repeatedly inside the collection box 3940, facilitating the better storage of the scraped ice and the absorbed chips inside the collection box 3940, preventing accumulation, making the ice in the collection box 3940 more compact, and facilitating subsequent processing by the staff. The parts not involved in this device are the same as or can be implemented using existing technologies.

[0043] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
